Indications for Use

aap's Cannulated Screws are intended for use over a guide pin or wire for bone fracture fixation and bone fragment fixation. aap's Washers may be used with the screws in certain applications. Specific indications, which are dependent in part on the diameter of the screw, include: scaphoid fractures and other fractures of the hand; metatarsal fractures and other fractures of the foot; malleolar fractures, ligament fixation of the proximal humerus; wrist, ankle, shoulder and elbow fractures; fractures of the pelvis and acetabulum: femoral neck and fractures: femoral supracondvlar fractures; and tibial plateau fractures.

Device Story

Cannulated bone screws and washers; used for bone fracture and fragment fixation; inserted over guide pin or wire. Manufactured from Titanium Alloy (Ti 6Al 4V E.L.I.) or 316L Stainless Steel. Used in clinical settings by surgeons for orthopedic procedures. Output is mechanical fixation of bone segments. Benefits include stabilization of fractures in various anatomical sites (hand, foot, limbs, pelvis). Distributed non-sterile; requires end-user steam sterilization per AAMI guidelines.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: Titanium Alloy (ASTM F-136-96, ASTM F-1295-97) and 316L Stainless Steel (ASTM F-138-92). Cannulated design for guide pin/wire insertion. Sterilization: Non-sterile, requires end-user steam sterilization per AAMI/ISO 11737 guidelines to achieve SAL 10^-6.

Indications for Use

Indicated for bone fracture and fragment fixation in patients requiring orthopedic stabilization, including fractures of the hand, foot, wrist, ankle, shoulder, elbow, pelvis, acetabulum, femoral neck, femoral head, femoral supracondylar region, and tibial plateau, as well as ligament fixation of the proximal humerus.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.
